Paint and Protective Coatings
Published in Ryan Cruzan, Manager’s Guide to Preventive Building Maintenance, 2020
Any building built before 1978 may have been painted with lead paint and could still have layers of paint containing lead. Unless you are fortunate enough to be able to apply a new coat of paint without disturbing the existing paint, any sanding, wire brushing, scraping, or washing could release lead dust. Many states require any disturbance of lead paint to be done by accredited lead abatement contractors and require any material removed to be handled as hazardous waste.

The present choices of lead analyzers focus primarily on paint analysis. They cannot perform analysis of lead in dust, dirt, or filters. The X-MET analyzer recognizes and addresses the total need of the lead abatement market. It is a field portable XRF analyzer that can perform analysis of various sample types, at levels exceeding the regulatory criteria. As a full-spectrum analyzer, it can compensate for the varying substrates encountered in analysis of lead in paint. Additionally, the collection of a full spectrum allows the instrument to analyze different sample types, such as filters, dust, and dirt. Detection limits and precision of analysis are easily obtained with short counting times of 5 to 10 s.
Sustainable Nanotechnology Development Using Risk Assessment and Applying Life Cycle Thinking

The U.S.EPA still spends millions of dollars of its shrinking annual budget on lead abatement. Lead is an elemental metal, and it cannot be further broken down. At one time, lead was used in gasoline, paints, and plumbing systems. Even though it is now banned from these uses, people are still exposed to lead, directly or indirectly, as a result of its prior use. Children still suffer from lead poisoning, mainly from exposure to lead paint. After years of exhaust emissions from automobiles that spread lead—first into the air, then to soils—those now living near major roadways may have lead in the food they grow. When the wind blows, lead in the soil can be entrained in the air and enter people’s nearby homes or workplaces. This lead and other pollutants then become part of the dust that people inhale and that young children can ingest while playing on the floor.
Direct-reading instruments for aerosols: A review for occupational health and safety professionals part 2: Applications

Lead abatement by scraping or sanding lead-painted surfaces can expose construction workers and others to lead aerosols. Using DRI, Choe et al. (2000) monitored the decay of particle concentration by size and validated that the mandated times between abatement, cleaning, and clearance were adequate to allow dust to settle and be amenable to cleaning.
